Geometric Design

An Empirical Assessment on the Effects of Geometry and Non-Geometry Factors in Work-Zone Crashes With Unobserved Heterogeneity

Work zones are uniquely configured and managed by special traffic signs, standard channelizing devices, appropriate barriers, and pavement markings. Unexpected driving conditions through different … [Read more...] about An Empirical Assessment on the Effects of Geometry and Non-Geometry Factors in Work-Zone Crashes With Unobserved Heterogeneity

Addressing the Motorcyclist Advisory Council Recommendations: Synthesis on Roadway Geometry, Pavement Design, and Pavement Construction and Maintenance Practices

Roadway geometry, pavement design, and pavement construction and maintenance practices are designed to construct and maintain roadway facilities that provide for motor vehicle travel. Typical … [Read more...] about Addressing the Motorcyclist Advisory Council Recommendations: Synthesis on Roadway Geometry, Pavement Design, and Pavement Construction and Maintenance Practices

Application of LiDAR and Connected Vehicle Data to Evaluate the Impact of Work Zone Geometry on Freeway Traffic Operations

Extensive literature exists regarding recommendations for lane widths, merging tapers, and work zone geometry to provide safe and efficient traffic operations. However, it is often infeasible or … [Read more...] about Application of LiDAR and Connected Vehicle Data to Evaluate the Impact of Work Zone Geometry on Freeway Traffic Operations

Maintenance of Traffic for Innovative Geometric Design Work Zones

Currently there are no guidelines within the Manual on Uniform Traffic Control Devices (MUTCD) on construction phasing and maintenance of traffic (MOT) for retrofit construction and maintenance … [Read more...] about Maintenance of Traffic for Innovative Geometric Design Work Zones

Doing More With Less

Scarce financial resources, limited rights-of-way, and continuing concerns about the environmental footprint of highway projects have compelled transportation officials to do more with less when … [Read more...] about Doing More With Less

Design of Construction Work Zones on High-Speed Highways

This report explores an approach for the selection of an appropriate construction work zone type; offers suggested guidance for the design of geometric features, including horizontal and vertical … [Read more...] about Design of Construction Work Zones on High-Speed Highways
